Air suspension issues in 4th Gen 1500

[Usawme]

Hi all, i have a customer who has a 4th Gen 1500 with factory air suspension and its all playing up. Takes 10 minutes to inflate some days, sometimes works fine other times leaves him stranded and constantly says lifting but takes forever to lift. Randomly airs out on him etc.

Is this a common occurrence? Is the air suspension a separate module for the MCU and control system or is it integrated with say the bcm etc?
Am working out if we switch out the oem air control for say accuair elevel plus or something similar which i typically deal with all the time or convert back to springs.

If we do go the conversion are all the mounting points the same as the factory suspension mounting points so can just take bags out and put springs / shocks back in?

Thanks for your time.

Anywhere that has as much information or diagrams / locations on the factory air suspension systems components would be great.

Cheers,
Darcy

The above thread has the parts list for a spring swap. I recently deleted mine. The issues your describing sound like valve block and possibly compressor. However bag leaks could be contributing to the issue.

Glad to hear, no more cold climate problems for you!!!

Thanks for that! I have been doing some digging and it seems to be a long list of problems with the onboard system.

I'm assuming all the bag info could be deleted from the computer by a dealer?


I'll price up a full aftermarket control system from autolevel system, compressor, valve block etc and just keep bags as they are and adapt to an aftermarket height sensor system and then also price springs and shocks. I'm assuming both will be quite expensive here in Aus we will probably struggle to find oem springs and shocks so aftermarket equivalents might be up there but will see what prices we come up with.

Mine was deleted via an alpha obd programmer to remove the system from the bcm and 2 fuses removed 5 and 40 if I remember correctly to disable the system. I went with bilstein for the shocks/struts and am so far happy, but I think eibach are a bit better
